Document Summary
Phy 121 lecture 11/20/16 acid precipitation and nuclear physics. Power plants can cause o2 to latch on to acids which can create acid rain which is very harmful. Sulfur dioxide can latch on to o2 or dissolve into water, caused from burning coal to heat up boilers. Things become basic when h+ is taken away and more acidic when h+ is added. Acid rain is typically 4. 2-4. 4 ph, very rare occurrence. Oxygen is mostly o2 but some ozone (o3) exits. (o) + (h2o) = (oh-) which is a hydroxyl radical. +can combine with other molecules to create different acids. Coal is a major source of fuel for power plants. Oil is a major source of fuel for pollution created by transportation. If you reduce temperature of a hot reservoir you reduce production of nitrogen oxide but also lose efficiency. Impacted sectors: aquatic, terrestrial, materials and human health. (1) aquatic: most affected. Soil can act as a buffer neutralizing some acids.
